a1 and a2 ram slots not working - Asrock Xtreme11 one Ram Dimm slot not working | Tom's Hardware Forum 888 slot 35

Hi, I have bought Asrock Xtreme 11 motherboard with 'Gskill Trident X F3-2400C10Q-32GTX RAM'. mobo has 8 dimm slots namely a1,a2,b1,b2,c1,c2,d1,d2. The problem is c1 is not working. I checked individual ram sticks and they are working perfectly. But whenever i insert any stick into c1, it is...

In a single memory processor with a populated capacity of 24 GB, install the 4 GB memory modules in slots A1, A2, A3, A4, A5 and A6.

Main mình slot ram nó thế này A1 B1 A2 B2. Trước đấy gắn slot B1, B2 thì máy chạy hoàn toàn bình thường, bật XMP, OC Ram các kiểu OK.
